v This invention relates to water heaters and particularlyto that class adapted to be attached to hot air furnaces, boilers or the like for'heating water in a tank separate from the furnace or boiler and one feature ofthe invention is the provision of means for extending a volume of water in position to be heated from a furnace, without perforating or entering the fire box portion of the furnace.-

A further feature of the invention is the provision of means for adjustably attaching the heating element to parts of the furnace structure. o v

A further feature of the invention is the provision of means for connecting the heating element to a conventional water tank;

ther objects and advantages willbe hereinafter more fully set forth and pointed out in the accompanying specification. 7 In the accompanying drawing which is made a part ofthis application, I 1 v Figure 1 is a sectional View through the heating element and upper portion of a hot air furnace with the water tank in elevation. Figure 2 is asectional view as seen'along line 22, Fig. 1,-on anenlarged scale.

'Figure 3 is a sectional view as seen'along line 33, Fig. 2. v

Figure 4 is a'sectional view as seen along line ir-4, Fig. -3,'and' a Figure 5 is a the heater attached toga conventional hot water or steam boiler structure.

Referringto the drawing,-the numeral 1 designates the heatingelement of ahot air furnace and 2 indicates the hood or casing surrounding the same for forming a space 3 in which to heat air, these features, as well as the water tank 4, being of the conven- "49 tional or any preferred form.

Heretofore it has been customary to enter a heating coil through holes drilled through the wall of the fire box of the heating element, thereby weakening the wall of i. the fire box as well as positioning-the coil in the path of coal being entered in the fire box, the drilling operation and installation of the coil requiring a great deal of time as well as expense.

In the present instance, these obj ectiondetail sectional View showing 1931. Serial No. 522,919.-

able features are overcome, in that instead of entering a coil through the wall of the heating element 1, a heating drum 5 is extended through the wall of the hood 2 and. into the air space 3, preferabl'y in close proximity to the top end of the heating element, the outer end of the drum 5 having asubstantially ball like head 6, which head enters a socket 7 in a mounting plate 8, 'the plate being attached to the wall of the hood in any suitable manner, as by means of bolts 9. By

providing the substantially ball and socketconnection between the drum 5 and plate 8,

the drum 5-may be readily adjusted'with respect to the heating element 1, the drum 5 being heldin its adj usted position by means of adjusting screws 10; Secured in the outer end of the drum 5 is a sleeve 11, to which is attached acoupling member 12, towhioh is attached one end of a water return pipe 13, the opposite end of said pipe being attached to the water tank 4 at a point adjacent the upper end of said tank. In order to convey water into the drum 5 to be heated,:a pipe 14 is extended through the couplinglmember 12 and a distance into the drum, so thatthe water will be discharged nearthe inner end of the drum, thus subjecting the water to considerable-heat while passing from the-inner to the outer end of the drum.

The opposite end of the pipe 14 is connect: ed with the water tank 4, preferably adjacent the lower endithereof, the pipe being selcured in and centered with the coupling memberl2 and drum 5 by threading a bushing 15, onto that part of the pipe 14passing through the'coupling and into theendof the coupling. It will likewise be seen that the drum may be positioned substantially horizontal, although the wall of the dome and the plate 8 are at an angle to the longitudinal axis of the drum.

In operation, the water from the main is conducted through the tank 4 to a point adjacent the lower extremity thereof through a feed pipe 16 and passes thence through the pipe 14 into the drum 5, where the water is thoroughly heated. The expansion of the heated water will cause the water to flow from the drum 5 through the pipe 13 into the upper portion of the tank, from whence the water is conducted to any suitable point through a pipe line 17.

It will be seen that this form of heating element may be very cheaply manufactured and installed and that the several elements may be quickly and readily separated for cleansing or repair and again quickly reassembled and reinstalled. 7

As shown in Fig. 5, the heater may be intstalled with the usual form of'hot water or steam boiler and when so used, the drum 5 is entered through an opening 18 drilled through the outer boiler section 19, which opening is in direct line with the circulating openings 20 in the adjacent boiler sections and above the fire box 21 of the boiler, the steam or hot water passing through said circulating openings 20 thoroughly heating the water passing through the drum 5 and without coming in direct contact with the heat from the fuel within the fire box. When this device is attached to boiler constructions shown in Fig. 5, the drum 5 is necessarily of a smaller diameter than the diameter of the openings 20, so as not to interrupt the circulation of the water oristeam through said enings.

While the description and drawing illlustrate in a general way certain instrumentali-ties which may be employed in carrying the invention into effect, it is evident that many modifications may be made in the various details without departing from the scope of the appended claims, it being understood that the invention is not restricted to the particular examples herein described.

lVhat I claim is: 1. In liquid heating plants having a spur liquid circulating means serving to extend within a heating device having a hole in its sidewall therefor, a flange serving to be secured to a corresponding exterior surface of suchheating device, a sleeve formed on such flange, said sleeve having an opening therethrough which serves to register with the corresponding hole in the wall of' such heating device, a cylindrical housing disposed through said opening and serving to m extend within the heating device, said housing having an enlarged partly spherical surface which serves to fit and be rotated to dif ferent positions in said sleeve, and permit said housing to be adjusted angularly to ditf-erent positions as desired, said housing having a closure at both the outer and inner ends, a tube fixed through the outer end closure of said housing and extending well within said housing, a conduit connection formed through the wall structure of said housing exteriorly of the heating device, whereby liquid to be heated may enter said housing through said tube and exit therefrom through said conduit connection, and .means to adjustably lock said enlarged housing portion in said sleeve.

2. In liquid heating plants having a spur liquid circulating means serving to extend within a heating device having a hole in its side wall therefor, an angular flange serving to be secured to a corresponding angular exterior surface of such heating device, a sleeve formed :on such flange, said sleeve having an approximately horizontal "opening tli-erethrough which serves to register with the corresponding hole in the wall of such heating device, said open-ing converging toward the interior of the heating device, in a semi-spherical formation, a cylindrical housing disposed through said opening and serving to extendwithin the heating device, said housing having an enlarged portion having a semi-spherical surface which serves to fit and be rotated into the semi-spherical formation of said opening to make asubstantially draft andsmoke tight joint, and permit said housing to be adjusted angularly to different positions as desired, said housing having a closure at both the outer and inner ends, means to'adjustably lock said enlarged housing portion in said sleeve, a tube threaded through the outer-end closure of said housing and extending well within said housing and a conduit connection formed through the wall structure of said housing exteriorly of the heating device, whereby liquid to be heated may enter said housing through said tube and exit th-erefrom'through said conduit connection. I

In testimony whereof, I have hereunto set my hand on this the 5th day of March, 1931.
